  • Patent number: 5611978
    Abstract: Sintered moldings are produced by molding a mixture of a sinterable ceramic or metallic powder and polyoxymethylene or a copolymer containing a majority of oxymethylene units as binder to give a compact, removing the binder by treatment with a gaseous acid, and sintering the product, which comprises removing the binder using an acid which is solid at room temperature and sublimes or melts and evaporates at elevated temperatures.
